Answer:
B and C
Explanation:
Cells are the simpliest level of life and they make up tissues. They are made up of <em>cell organelles</em> not organs so it cannot be D (in case you were confused).
Hope this helped!
Answer:
Annual mean temperature and annual mean precipitation.
Explanation:
The major biomes of North American biomes include almost every one of these biomes, Tundra., Boreal, Deciduous, Prairie, Desert, montane and tropical. All these biomes are effects or influence the distribution of organisms by several biotic and abiotic factors as the organism is found in the biomes that help in their livelihood.
Abiotic factors that influence the biomes that are present in North America most are temperature and precipitation that can be measured in Annual mean temperature and precipitation.
Thus, The correct answer is - annual mean temperature and annual mean precipitation.
Answer:
0.549 is the frequency of the F allele.
0.495 is the frequency of the Ff genotype.
Explanation:
<em>FF </em>or <em>Ff</em> genotypes determine freckles, <em>ff</em> determines lack of freckels.
In this class of 123 students, 98 have freckles (and 123-98= 25 do not).
If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:
q²= 25/123
q²=0.203
q= 
q= 0.451
<em>q </em>is the frequency of the recessive f allele.
Given <em>p</em> the frequency of the dominant F allele, we know that:
p+q=1, therefore p=1-q
p=0.549 is the frequency of the F allele.
The frequency of the Ff genotype is 2pq. Therefore:
2pq=2×0.549×0.451
2pq=0.495 is the frequency of the Ff genotype.

Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.
